To all whom it may concem:

Be it known that I, HnNny A. House, J r., a citizen of the UpitedStates residing in, Springfield, inthe' county of Hlampden and State of Massachusetts, have invented certain new and useful Im rovemen ts in the Methods of Forming ipple Sockets in Wheel Rims; and I do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the senile, reference being had to the accompanying drawings, and to figures of reference marked thereon, to which form part of this specification. Like figures of reference refer to like parts.

This invention relates to methods of formin nipple sockets in wheel-rims. 2G

a method of forming sockets in wheel rims, without machining the same.

Another object is to form nipple sockets having angular depressions or seats for nipple heads, which shall resist the turning of the nipple when seated thereon.

My invention consists in carrying out certain operations upon any suitable devices,

in the development of nipple sockets.- at A set of devices adapted for such development is illustrated in the drawings, the operations are explained and what claim is set forth.-

In the drawin Figure 1 is a ont elevation offpart of a press used in the first operation 0 forming the sockets in the rim.

Figure 2 is a sectional side elevation of the parts shown in Figure 1.

, Figure 3 is a plan of the parts shown in Figures 1 and 2.

Figure 4 is a fragment of wheel rim showing the grouping of the nipple sockets after the first operation.

no object of this invention is to provide 'ciproca'tin Figure 8 is an enlarged sectional elevation of a finished socket, including the forming and punching dies.

, Figure 9 is a erspective view of the formin end of a ho ow punch.

igure 10 is a plan view of a fragment of rim, showing the finished nipple socket.

In the figures, referring particularly to Figures 1, 2, and 3, upon the born 1, of a pressing. machine not shown, is fixed' an impression block 2,'having hemispherical pits 3, 3, 3, into which is'sunk the metal of the rim 4, by means of the punches 5, 5, 5,

which are in sliding engagement with the guide block 6. Upon bracket 7, is adjustably fixed a block 8, in sliding engagement therewith, but fixed in osition by the set screw 9. Projecting up om the block 8, is

a cylindrical piece 10, which engages a reguide pin 11, spring-pressed downwar b the spring 12, which bears against an a justing screw 13. In Figure 3 are shown three impression unches 5, 5, 5,

passing through holes A, and G, in a guideblock't. In Fi re 4 are shown two rows of hemispherica pockets marked respectively. Dand E, there being twice as many" pockets in the row D as there are in the row E. One of the section in Figure 5;

pockets is shown in Referring toFigures 6 and 7, eccentrically mounted and inclined in position on parts of a forming andpunching press, is a rim 4, having two rows of hemis herical pockets, previously punched there n. The rim 4 angs upon a forming and punching die 14, resting upon a horn 15, of the press. The rim 4 is shown resting upon an inclined plate 16, which is supported upon brackets 17 and 1,8. The rims is also supported against pins 19 and 20, fixed to the plate 16. In Figure 8, the bottom of the hemispherical pocket. is shown formed into a pyramidal socket, by means of the hollow punch 21, shown resting thereon: A cylindrical punch 22 is in sliding engagement with the punch 21, which forms the hole 23, in the socket. In Figure 9, the hollow punch 21, is shown having a four fiat-sided end 24, and a hole 25. In Fi 1' re 10, a hemispherical pocket 26, is shown '1' swing a po'iygnnal and In Early depressed socket 2i,

With the devices as herein illustrated and above described, my methodof forming nipple sockets is as follows 'To begin with, a rim 4, is hung upon the block 2, and the three hemisphericalend-ed punches' 5, 5, 5, occupying the holes A, B and C, in the guide 6, are forced down upon the, rim 4, causing the metal thereof to sink into pits 3, 3, 3, and form hemispherical pockets like that shown in Figures 4 and 5. Two of the pockets are adjacent to one flange, and one is adjacent to the other flange of the rim 4. The punches are next raised and the rim 4 is turned, so that the guide pin 11, rests in one of the pockets previously formed, the pin 11 having previousl been properly positioned by so setting t e block 8, as to give the desired spacing to sets of pockets punched. After completing the formation of hemispherical pockets in the: rim, the same is taken to the socket forming and hole punching machine, parts of which are shown in Figures 6 and 7.

The rim 4 is placed upon the plate 16, and hung upon the block 14, having the convex side of the pocket resting in a specially formed pit 14, having a hole 14", for co-operation with the punching pin 14".

The spokes of a wire wheel make various angles with the rim as they connect with the hub of the wheel, but they may be grouped according to the angle at which they stand.

The socket forming and punching machine has its arts so made and arranged as to form soc ets suited to a given group of spokes.

The pitin the block 14, is positioned so that the center of a pocket resting thereon, is on or near the axis of the punch or forming die. The socket forming die is then tarmac If the angle at which the axis of the socket is to stand in the rim is not much from the radial direction, then the first operation of making hemispherical pockets may be dispensed with and the socket may be formed as the first operation, and the punching of the hole as the second. 1

Having described my invention I claim, 1. The method of treating metal rims for wire spoked wheels in which the spokes are inclined at various angles, consisting in, first forming hemispherical indentations by a punch operating at right angles to the surface of the rim, second reshaping a portion of the inner wall of the depression by a pyramidal punch operating at an angle to the surface of the rim other than a right angle and third, perforating said depression at the center of the reshaped portion by a punch operating at the same angle as the pyramidal punch.

2. The method of treating metal rims for wire wheels in which the spokes are inclined at various angles consisting in first,

forming hemispherical depressions by a punch operating at right angles to the surface of the rim, second, marking the inner walls of each depression andthird, perforating each of said depressions by a punch operating in the line in which the spoke to be inserted will extend.
